NGC 523, also known as NGC 537, 4ZW 45, Arp 158, CGCG 521-22, IRAS 01225+3345, MCG 6-4-18, PGC 5268, UGC 979, and V V 783, is a spiral galaxy located in the constellation Andromeda. It was discovered separately by William Herschel on September 13, 1784, and by Heinrich d'Arrest on August 13, 1862. d'Arrest's discovery was listed as NGC 523, while Herschel's was listed as NGC 537; the two are one and the same. John Dreyer noted in the New General Catalogue that NGC 523 had a double nebula.
